PIN-HOLDER FOR ELECTRIC-WIRE INSULATORS.

SPECIFICATION forming part of Letters Patent No. 355,165, dated December 28, 1 886.

Application filed October 20, 1886. Serial No. 216,707. (No model.)

Be it known that I, MACK HANKS, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Telegraph Pin -Holders for Insulators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which .form a part of this specification. I

The object of this invention is to provide a metal holder or bracket for the screw-pin and glass insulator screwed thereon, for telegraphlines, and of such a shape and construction that it can be fastened to the under side or sides of the cross-arms or against the side of a telegraph-pole, thereby giving additional wire-holding room, or it may be fastened to a window-easing at top or sides, or against a brick wall by screwing it between the bricks in the mortar.

The invention as constructed will be understood by the following specification and claim:

In the drawings, Figure l is an elevation of a telegraph-pole, showing my device attached to the under side of a cross-arm, Fig. 2 showing it attached to a window casing; Fig. 3,

with screw-pin and cup thereon.

A represents the metal holder, constructed of a fiat piece of iron bent over at the top at right angles to the body or back, as at a, and also bent at the bottom 7) forward, and so as to form an arm and a hollow or socket, b, for the insertion of the upright wooden screw-pin l B, which is screwed into the glass insulator O,

as usual. At the top, in the part a, are twoholes for screws, so as to fasten it to the under side of cross-arms or to the upper longitudinal part of a window-casing and keep the insulator always vertical. In the back are also two holes, (I d, for the insertion of screws or nails to fasten the.holder A to the sides of cross-arms, poles, buildings, brick walls, and otherplaces. For brick the holes will be just far enough apart to allow the screws to penetrate into the mortar each side of a brick. In the side of the socket b is another hole, 0, to fasten the screw-pin B therein.

Thissimple device will be found of great utility for the purposes described, especially in running wires through windows into offices,

in adding to the wire-holding capacity of poles and cross-arms and other places, and to take the place of the white porcelain knobs, which do not insulate as well as glass. 7

The whole bracket A and pin B may be made in one piece, and all of metal, if desired; but I prefer the pin of wood and separate, as

-it is cheaper, and it is difficult to get the proper screw-thread on the metal pin. I claim--- The metal holder A, consisting of the arm a, which is made or bent at right angles to the back or body, and having holes therein, the bottom bent-forward into an arm, I), and formed into a socket or holder, 1), andin combination with a screw-pin, B, all substantially as and for the purpose specified.

In testimony whereof I affix my-signature in presence of two witnesses.

MACK HANKS.
